There is no neuromuscular junction (NMJ) in smooth muscles because smooth muscle fibers are not innervated by motor neurons in the same way as skeletal muscles. Instead, smooth muscle cells receive signals through varicosities, which are swellings along autonomic nerve fibers that release neurotransmitters directly into the surrounding tissue. This allows for a more diffuse and widespread response, suitable for the involuntary and rhythmic contractions of smooth muscle found in organs. Additionally, smooth muscles can also respond to hormones and local chemical signals, further differentiating their control mechanisms from those of skeletal muscles.
